Question

now, plot the points to represent the aircrafts elevation 0, 1, 2, 3 and 4 minutes after reaching cruising altitude.
time since reaching cruising altitude (min) | elevation (ft)
0 | 35,000
1 | 35,000
2 | 35,000
3 | 35,000
4 | 35,000
what is the slope of this line?
the slope is
enter

Explanation:

Step1: Recall slope formula

The slope \( m \) between two points \((t_1, e_1)\) and \((t_2, e_2)\) is \( m=\frac{e_2 - e_1}{t_2 - t_1} \).

Step2: Choose two points

Take \((0, 35000)\) and \((1, 35000)\) (any two points from the line work).

Step3: Calculate slope

Substitute into the formula: \( m=\frac{35000 - 35000}{1 - 0}=\frac{0}{1}=0 \).

Answer:

\( 0 \)
